This is a mod that will make the fret buttons on your guitar hero controller firmer and more responsive. You get less of that clicking / rattling sound you get when you're playing fast, and it requires less downward pressure to fret a note.
You will need:
Guitar Hero controller
Size 10 Torx screwdriver
Small philips screwdriver
Large-ish flat screwdriver
Duct tape (I used black "Duck" tape)
"Blu-tack", or other poster adhesive putty (e.g. "white-tack")
This idea is not mine as people have done similar things before, but there is no instructable, or indeed any clear set of instructions that I could find. And I haven't found any examples of people doing it to a Guitar Hero 3 controller, although the principle is the same for other GH guitar versions.
This is my first instructable so please be kind :)
Step 1: Remove all screws in the guitar neck
After removing the neck from the guitar body, remove all the screws from it (excluding the one holding on the strap button, unless you don't use it, and want to remove it - I have).
You will need a size 10 Torx screwdriver for this.
